System-specific DDR5 UDIMM for ASUS Z890 APEX

This 32 GB DDR5 4800 module is built for the ASUS ROG Maximus Z890 APEX motherboard. It arrives new as a single 288-pin UDIMM rated at 1.1 V with CL40 latency. The 2Rx8 organisation uses major OEM DRAM chips for desktop workloads.

Builders matching the exact APEX qualification

The part is validated for that specific board and will not suit systems requiring registered or ECC memory. Buyers needing a heat spreader or multiple matched modules should look at other kits.

Single 32 GB 2Rx8 rank at 4800 MT/s

The 2Rx8 density on one stick determines whether the board can fill its slots as planned. Confirm the platform accepts a single-rank-per-channel population before ordering.

Questions about this item

Does the 288-pin DDR5 UDIMM fit the ASUS ROG Maximus Z890 APEX slots?

Yes, the module uses the standard 288-pin DDR5 UDIMM form factor that matches the board's DIMM sockets.

What is the correct way to seat the single 32 GB stick, and what step is often missed?

Align the notch with the slot key, press firmly until both retention clips click, then verify the motherboard reports 4800 MT/s in BIOS.

When should the 2Rx8 CL40 1.1 V module be replaced or checked?

Replace if memory diagnostics report errors or the system becomes unstable; otherwise the module has no scheduled maintenance interval.
